ACCELEROMETER BASED CONTROLLER, CONTROLLED DEVICE AND CONTROL METHODS THEREOF

摘要

An accelerometer (101, 202) based controller (102), a controlled device (104) and control methods thereof. The controller (102) is adapted to control the controlled device (104). In response to hand movement, the accelerometer (101, 202) in the controller (102) produces acceleration and/or angle signals. The signals are sent to a processor (204) in the controller (102). The processor (204) is configured to determine a trajectory based on the signals and/or identify a command which is used to control the controlled device (104). The controlled device (104), for example, a cleaning unit for washing windows, can be secured to, for example, a window. Upon identifying the command from the controller (102), the controlled device (104) can respond to the command. The command can be instructions for the controlled device (104) to move about the window and/or activate a cleaning system.
